Researchers say that infrared technology holds the potential to spot from afar whether a site is being used to make nuclear weapons. They developed a model which precisely characterizes the material in each pixel of an image taken from a long-wave infrared camera. The U.S. National Nuclear Security Administration (NNSA) funded the project. The government’s long-term goal for infrared technology is remotely to detect the exact materials, chemicals and gases coming and going from factories or other sites suspected of illegal nuclear production.

The negotiations between the P5+1 and Iran over Iran’s nuclear program continue, with an eye to replacing, by June, the current temporary agreement with a permanent one, but Israel let it be known that it is continuing to its preparations for a military strike on Iran’s nuclear facilities. Prime Minister Benjamin Netanyahu and Defense Minister Moshe Ya’alon have instructed the IDF to continue its preparations for carrying out such a strike, at a cost estimated to be at least ten billion shekels ($2.89 billion) this year.

The White House’s fiscal 2015 budget proposal includes more than $220 million in cuts for nuclear security initiatives such as the International Material Protection and Cooperationprogram, which aims to secure and eliminate vulnerable nuclear weapons and materials, and the Global Threat Reduction Initiative, which supports the Energy Department’s efforts to prevent terrorists from acquiring nuclear and radiological materials that could be used in weapons of mass destruction. The administration says that 54 percent of the reduction in the administration’s nonproliferation budget request can be accounted for by the decision to halt the South Carolina Mixed Oxide Fuel Fabrication Facility(MOX), which would have convert weapons-grade plutonium into nuclear reactor fuel, because the project proved to be too costly.

Three Republican lawmakers from South Carolina — Senator Lindsey Graham and Representatives Tim Scott and Joe Wilson have – have asked South Carolina governor Nikki Haley to “explore any legal avenues” to prevent the mixed-oxide fuel (MOX) project at the Savannah River Sitefrom shutting down. The administration has decided to put the project on hold after repeated delays and cost overruns averaging 60 percent over the original estimates.

The Obama administration has decided to put on hold its plans to complete construction on a South Carolina reprocessing facility which would convert nuclear weapon-grade plutonium into reactor fuel. The suspension of work on the project is part of the fiscal 2015 budget plan the administration unveiled Tuesday. The project has been hobbled by delays and massive cost-overruns, and experts says security and safety concerns have not been adequately addressed.

The Obama administration 2015 budget proposal shows that the administration will spend less on nuclear nonproliferation initiatives in 2015 than it would in 2014. The budget of the National Nuclear Security Administration (NNSA), the agency responsible for various nuclear weapons and nuclear nonproliferation programs, will be cut by 20 percent, from the $1.9 billon Congress approved for fiscal 2014 — which in turn was a $289 million cut from fiscal 2013 levels — to $1.6 billion in 2015.

The Mixed Oxide (MOX) nuclear fuel factory at the Savannah River Site in South Carolina, being built to help dispose of cold war-era weapon-grade plutonium, would cost up to $30 billion in addition to the $4 billion spent on construction so far. The staggering cost overruns have led many to call for a new, less expensive solution. Matthew Bunn, a former Clinton White House official who helped develop the plutonium disposal program, agrees that the cost of the MOX factory is excessive. “The things we’re trying to accomplish aren’t worth that amount of money,” he said.

The International Atomic Energy Agency (IAEA) reports in its quarterly inspections assessment that the quantity of 20 percent enriched uranium in Iran’s hands has been reduced since last November, when the world’s six powers (P5+1) and Iran have reached an interim agreement on Iran’s nuclear activities. Iran now has 354 pounds of the material — or about one-fifth less than what it had in November. With the right type of centrifuges, it is quicker to enrich uranium from 20 percent to weapon-grade 90 percent than it is to enrich uranium from 1 or 2 percent to 20 percent, so that the smaller the amount of 20 percent uranium a country has, the longer the “breakout” time — the time it would take a country to assemble a nuclear bomb once a decision to do so has been made.

Iran said that in exchange for Iranian oil, Russia could build a second reactor at Iran’s Bushehr nuclear power plant. Russia could also provide Iran with trucks, railroad tracks, mini-refineries, grain, and other goods for Iranian oil. In a deal worth $1.5 billion a month, Iran would export 500,000 barrels of oil per day to Russia. The deal would increase Iran’s oil exports, which have been reduced to about one million barrels a day by American and European sanctions aimed at curbing Iran’s nuclear program.

Threats of terrorism and weapons of mass destruction do not seem as imminent today as they did after the 9/11 attacks, but Jill Hruby, vice president of International, Homeland, and Nuclear Security at Sandia Labs, says that scientists, industry, and universities working on technological solutions to national security challenges must anticipate what could come next. Speaking at AAAS annual meeting, Hruby said that in an environment of lower public interest — due, in part, to the success of early efforts to combat terrorism that resulted in fewer major incidents in recent years — continued collaboration between national security laboratories, academia, and industry is needed.

There are more than 5,000 medical and research devices in the United States containing high-activity radiation sources, including 700 with category-1 sources. Category-1 radiation material could be used by terrorists in dirty bombs. The security measures developed by the industry were written with accident prevention in mind, not in order to thwart a deliberate, forcible effort by terrorists or criminals to gain control of the toxic material. In addition, radioactive materials were considered to be “self-protecting,” because it was assumed that the powerful radiation would deter anyone thinking of tampering with these devices. Terrorist bomb-makers, however, showed themselves to be more technologically-savvy than earlier thought, and, in any event, suicide bombers would not be deterred by the risk of radiation poisoning.

The U.S. National Nuclear Security Administration (NNSA) announced the successful completion of the first full-system mechanical environment test of the B61‑12 as part of the NNSA’s effort to refurbish the B61 nuclear bomb. This first full-system mechanical environment test is one of several critical milestones for the B61-12 Life Extension Program (LEP). The B61-12 will replace the existing B61-3, -4, -7, and -10 bombs. Fielding the B61-12 will also enable the retirement of the B83, the last U.S. megaton class weapon, in the mid-to-late 2020s.

Post-detonation nuclear forensics relies on advanced analytical techniques and an understanding of the physio-chemical processes associated with a nuclear detonation to identify the device type and the source of the nuclear material in the device. Researchers have begun to develop a technique that provides a practical approach for looking into the complex physical and chemical processes that occur during fallout formation following a nuclear detonation.

Three former U.S. Air Force officers have alleged that USAF officers responsible for operating nuclear-armed missiles at Malmstrom Air Base in Montana have, for many years, been cheating on monthly readiness tests, and were never punished for it. The former officers claim that cheating is the norm and that officers who did otherwise are the exception.The officers who made the allegations added, though, that misconduct on tests did not impair the safety of the nuclear weapons or the Air Force’s ability to launch missiles if ordered.

A new study says that only broad and verifiable changes to Iran’s current nuclear program could serve as a basis for a permanent nuclear deal between Iran and the international community. Among the changes: reducing the number of Iran’s uranium-enrichment centrifuges from the current 19,500 to no more than 4,000, and limiting Iran to one enrichment site; converting the heavy-water reactor being built in Araq to a light-water reactor fueled by low-enriched uranium; and imposing a tight, intrusive inspection regime for at least twenty years.

The long view

As North Korea fired off a series of missiles in recent months — at least 18 since May — President Trump has repeatedly dismissed their importance as short-range and “very standard” tests. And although he has conceded “there may be a United Nations violation,” the president says any concerns are overblown. Kim Jong-un, North Korea’s leader, Mr. Trump explained recently, just “likes testing missiles.” American intelligence officials and outside experts have come to a far different conclusion: that the launchings downplayed by Mr. Trump, including two late last month, have allowed Mr. Kim to test missiles with greater range and maneuverability that could overwhelm American defenses in the region.

Politicians’ tweets can sometimes reveal new intelligence about their own country’s military capabilities and programs. On August 28 the official Twitter account of the Vice President of India, Shri M. Venkaiah Naidu, tweeted photos of his visit to the country’s Naval Science & Technological Laboratory. Among the missiles and unmanned vehicles is a sub-scale model of a submarine. And it appears to be not just any submarine – the model may offer the first visual clues to India’s next-generation ballistic missile submarine, the S-5 Class.

Iran said Saturday it had accelerated its nuclear research work and threatened to take fresh steps within a month that could allow it to expand its stockpile of enriched uranium, a material that can be used to fuel a nuclear weapon. The move comes after Europe failed to meet a deadline Iran set in July to offset the impact of U.S. sanctions.
